synthetic oils do not require the warm up periods mentioned above. Very old school. If your engine is clearanced tight with aluminum heads then maybe a bit of warmup is required to let the heads expand, if you are running solids or a solid roller cam. But generally, todays engines are clearanced "loose" for both performance and fuel mileage, and they also take advantage of better materials used in their constructions. (the build)
A racing wet sump, together with the proper windage setup AND a vacuum system will give you the same horspower net gains you would get with a dry sump, on a purpose built engine. No differance there guys. OF COURSE a dry sump is better for cars that are tossed around hard though.
As for the road clearance issues;
A engine can indeed be set down lower in a car to take advantage of a dry sumps lower pan height. But to do so though, in a way, you are designing a car around the dry sump. See my next paragraph for the disadvantages.
I am puting the parts together fo a dry sump conversion on my car. But my cars engine height was set with a wet sump pan in mind. And on my dry sump conversion, I for sure, am not going to set the engine in lower either. The reason being that the lowest part of my cars road clearance is at the flywheel bell housing and not at my original custom wet sump pan. Regarding custom built cars using dry sumps, they would have to address tranny clearance issues to take advantage of a lower pan height on a dry sump. Of course in a racing type car you can set the engine in lower than you can for a street type car. Nothing new there.
And I, for the life of me can't understand why you would want to run a accusump pre oiler system with a dry sump system. With a dry sump all you would have to do is turn on the
oil pump under the reservoir tank prior to starting your engine. I must be missing something here. We put on dry sumps to do away with things like accusumps I thought.
